What is role of CPU instruction set? Detailed explanation of CPU instruction set knowledge in Processor Options
The CPU is equivalent to brain of human body. It is one of main hardware of a computer and determines computing performance of a computer. As for basic knowledge of CPU, editor has popularized a lot of scientific knowledge for most users, but recently a netizen asked editor, "What is role of CPU instruction set in CPU parameters?"!
I believe that when you query for a specific CPU model, there is a CPU instruction set parameter, as shown in figure below.
Regarding CPU instruction set, there is not really an in-depth study for general users. Here we understand functions and related knowledge about CPU instruction set in an easy to understand way.
What is function of CPU instruction set?
CPU instruction sets are stored internally by CPU, mostly complex programs that optimize and control operation of CPU. With these instruction sets, CPU can run faster and more efficiently. Each instruction organized by system requires CPU to execute according to a preset instruction, and these preset instructions are collectively referred to as CPU's instruction set.
The CPU relies on external instructions to "activate" memory instructions to control and compute computer. Generally speaking, more instructions stored in a preset, smarter CPU, and more advanced instructions stored in a preset, more advanced CPU. called instruction set.
The more instruction sets a processor has, better?
The number of CPU instruction sets has a big impact on efficiency of CPU, but for normal users, this feature is almost irrelevant. Processors with fewer instruction sets, such as RISC, can also perform all functions, but they only consist of simple instructions, so they take longer to complete.
I still remember last year's God U Pentium G4560 processor. Compared to i3 processor, three instruction sets have been trimmed, namely AVX, AVX2, and FMA3. This does not affect ordinary households and gamers, but it has a big impact on render designer.

The above is a brief introduction to relevant knowledge about CPU instruction set. In fact, for non-professional general users, there is no need to care about CPU instruction set parameter at all. Enough to care more about CPU performance. As for CPU performance, good or bad, you can refer to CPU ladder diagram.
